Structures of the oral cavity. The oral cavity is bounded by the teeth tongue hard palate and soft palate. These structures make up the mouth and play a key role in the first step of digestion. Although the oral cavity is a small anatomical structure in the human body it is a significant part of the digestive system.

It has two divisions four walls and two openings. The oral cavitys anatomical structures include lips cheeks gums teeth the tongue soft. Oral cavity Figures 11 12 13 and 14 and how the following structures function within it.

Periodontium the supporting structure of the tooth. Salivary glands and saliva. ORAL EMBRYOLOGY A basic understanding of the development of the face oral cavity and jaws in.

The oral cavity is situated anteriorly on the face under the nasal cavities. It is bounded by a roof a floor and lateral walls. Anteriorly it opens to the face through the oral fissure while posteriorly the oral cavity communicates with the oropharynx through a narrow passage called the oropharyngeal isthmus also termed the isthmus of the fauces.

The oropharyngeal isthmus is. This article presents an overview of the structures of tooth oral cavity The salivary glands the bones of the jaw and the articulations between the jaws temporomandibular joints. Teeth constitute approximately 20 of the surface area of the mouth they have several functions including Mastication Speech.

Need a basic understanding of oral cavity anatomy Figures 11 and 12 and how the following structures within it function. Teeth including dentition Periodontium the supporting structure of the tooth Tongue Saliva MAIN FUNCTIONS OF THE ORAL CAVITY The oral cavity is uniquely designed to carry out two main functions. Begin the process of digestion.

The floor of the oral cavity consists of several structures. Muscular diaphragm comprised of the bilateral mylohyoid muscles. It provides structural support to the floor of the mouth and pulls the larynx forward during swallowing.

Geniohyoid muscles pull the larynx forward during swallowing. Vestibule buccal mucosa opening of the salivary ducts floor of the mouth soft palate uvula and bottom surface of the tongue. Specialized mucosa of the tongue.

Modified mucosa of the top of the tongue. Oral cavity proper boundaries. The oral cavity is lined by a mucous membrane the oral mucosa consisting of a stratified squamous epithelium which may or may not be keratinized and an underlying connective tissue layer the lamina propria.

The surface is kept moist with mucus produced by. Structure of the oral cavity Oral cavity The oral cavity is limited by the palate the base of the mouth the cheeks and the lips as well as by the uvula and the palatine arches on each side of the uvula. Minor salivary glands which wet the inner surfaces of the lips are located between the muscle and the inner lip tissue labial mucosa labial mucosa.

Soft wet inner tissues of the insides of the lips extends from canine to canine inside lips. Elevation at the midline of the upper lip. The oral cavity is surrounded by the lips and is composed of two separate regions the vestibule the area between the cheeks teeth and lips and the oral cavity proper.

The oral cavity proper is mostly filled with the tongue and bounded anteriorly and on the sides by the alveolar processes containing the teeth and posteriorly by the isthmus of the fauces. Continuous with the vermilion border of the lip is the oral mucosa. Given the multiple structures that make up the oral cavity abnormalities can abound.

Many are overt and many are subtle. Common abnormalities of the teeth and associated structures include caries pyorrhea plaque periodontal pockets and periapical abscesses Figure 1293. The Oral Cavity and Associated Structures.

A tooth Figure 1291 consists of a crown and a root. The crown is covered with enamel and the root is covered with cementum.

Importance Of Structure And Function. An ideal reconstruction of the oral cavity is one that very closely resembles the original structures in both form and function. To approach this ideal the interactions between structures both within and beyond the oral cavity must be considered Fig.

The oral cavity can be divided into two parts. 1 the oral vestibule which is the space between the lips or cheeks and the teeth and 2 the oral cavity proper the region medial to the teeth. A mucous membrane of stratified squamous epithelium lines and protects the inside of the mouth.

The oral cavity is lined by a mucous membrane the oral mucosa consisting of a stratified squamous epithelium which may or may not be keratinized and an underlying connective tissue layer the lamina propria. The surface is kept moist with mucus produced by. Mouth also called oral cavity or buccal cavity in human anatomy orifice through which food and air enter the body.

The mouth opens to the outside at the lips and empties into the throat at the rear. Its boundaries are defined by the lips cheeks hard and soft palates and glottis. It is divided into two sections.

The vestibule the area between. Oral cavity The major structures of the oral cavity are the lips teeth tongue oral mucosa and salivary glands. The primary function of the oral cavity is in prehending masticating and moistening of food.

The latter two functions prepare food for deglutition swallowing. Oral Tissues and Structures. Landmarks of the oral tissues include the palate tongue cheeks and floor of the mouth.

It is significant to recognize the normal appearance of these structures during an intraoral examination of the patient. Fauces Passageway from oral cavity to pharynx.
